Perceived Stress Scale

TLDR

The study evaluated the reliability and validity of the PSS‑10 in Brazilian adults. A two‑stage translation produced a Portuguese version of the PSS‑10, which was administered to 793 university teachers. Exploratory factor analysis identified two factors explaining 56.8 % of the variance, with Cronbach’s alphas of 0.83 and 0.77 and test‑retest reliabilities of 0.83 and 0.68, and correlations with perceived health ranging from –0.22 to –0.35, demonstrating adequate reliability and validity.

Abstract

The perceived stress scale (PSS-10) reliability and validity were evaluated in Brazilian adults. A two-stage translation procedure was employed to achieve a Portuguese version. Participants were 793 Brazilian university teachers. The exploratory factor analysis showed two factors with eigenvalues greater than 1.0 (56.8% of variance). The Cronbach’s alpha coefficients were 0.83 (Factor 1), 0.77 (Factor 2) and 0.87 (Total Score). The test—retest reliability scores were 0.83 (Factor 1), 0.68 (Factor 2) and 0.86 (Total Score). PSS-10 and perceived health correlations ranged from —0.22 to —0.35. The PSS-10 showed an adequate reliability and validity supporting its use in this population.
